Growth of the cobalt nanowires using AC electrochemical deposition on anodized aluminum oxide templates

Abstract

The nanopore arrays were fabricated by a two-step anodization of aluminum in an aqueous solution of 0.3 M oxalic acid at the temperature of 6 °C by applying a constant direct current (DC) of 40 V. A template-assisted synthesis of Co nanowire arrays was carried out by electrodeposition into the pores of prepared AAO templates. Cobalt (Co) nanowires of high density and uniformity were synthesized via an electrochemical deposition of metallic Co nanoparticles using a nanoporous template of anodized aluminum oxide, by applying an alternative current (AC).
